With Chicago Mayor Rahm Emanuel not running for another term, the field of candidates in the running to replace him is the largest in recent history at 14.
Unless a candidate gets more than 50 percent of the vote - a very unlikely scenario, the top two vote-getters will head to a runoff election in April.
In addition to the wide-open race for mayor, the position of city treasurer and all 50 seats on City Council are on the ballot as well, plus plenty of local referendum questions.
With complete coverage of the municipal elections both online and on television, the app and website will house live, updated election results for voters to watch Tuesday evening.
Live coverage can be watched online and on television beginning at 10 p.m.
